Building Android apps starts with a well-defined goal and an awareness of device variability. Outlining the MVP, choosing an architecture, and mapping key user flows early helps keep the initial release focused and minimizes rework as the app expands.

Once the foundation is set, focus shifts to a consistent UI, performance, and compatibility across different OS versions and screen sizes. Robust state management, prudent networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
